Is there a maximum amount of times you can extend in a 6 month period or a year period? I came in on a UK passport in January and then extended for 30 days and left in March. I will be again coming to Thailand for around 70 days and just wondering the best way of doing this? At the moment I’m thinking staying roughly 25 days then fly to somewhere else (possibly Hanoi) and then come back with a 30 day visa exemption and extend it? I won’t be able to do a visa before I arrive but is it possible to do it whilst I’m there and avoid the need to travel outside the country?
